Soft Agar Clonogenic Assay

Three new steroid biglycosides, plancisides A-C (1-3), were isolated from the ethanolic extract of the starfish Acanthaster planci. The structures of 1-3 were determined by extensive NMR and ESI-MS techniques, as (24 S)-28- O-[β-D-galactofuranosyl-(1→5)-α-L-arabinofuranosyl]-24-methyl-5α-cholestane-3β,4β,6α,8,15β,16β,28-heptol (1), (24 S)-28- O-[α-L-fucopyranosyl-(1→2)-3- O-methyl-β-D-xylopyranosyl]–24-methyl-5α-cholestane-3β,4β,6α,8,15β,16β,28-heptol (2) and (24 S)-28- O-[2,4-di- O-methyl-β-D-xylopyranosyl-(1→2)-α-L-arabinofuranosyl]-24-methyl-5α-cholestane-3β,4β,6α,8,15β,16β,28-heptol 6- O-sulfate (3), respectively. Compound 2 is the first steroid glycoside containing an α-fucopyranose unit found from starfish. Compound 1 slightly inhibits cell proliferation of HCT-116, T-47D, and RPMI-7951 cancer cell lines, but has no effect on colony formation of these cells in a soft agar clonogenic assay.

Two new asterosaponins, lethasteriosides A (1) and B (2), were isolated along with previously known thornasteroside A (3), anasteroside A (4), and luidiaquinoside (5) from the ethanolic extract of the Far Eastern starfish Lethasterias fusca. The structures of the new compounds were elucidated by extensive NMR and ESIMS techniques, and chemical transformations. Compounds 1 and 3–5 did not show any apparent cytotoxicity against cancer cell lines T-47D, RPMI-7951, and HCT-116, but glycoside 1, at concentration of 20 μM, demonstrated considerable inhibition of the T-47D (97%), RPMI-7951 (90%) and HCT-116 (90%) cell colony formations in a soft agar clonogenic assay.
